Before we explain sleep apnea, let's quickly break down how breathing works. When you're awake, the muscles of your throat act to keep the airway straight and open so air can flow in and out of your lungs. When you sleep, these same muscles relax and your throat gets narrower. Normally, this doesn't close the airway, it just slows down breathing during sleep.
